Waste plexiglass recycling method

Abstract

The invention belongs to the technical field of plexiglass recycling, and in particular relates to a waste plexiglass recycling method. The method uses a cracking device; the cracking device comprisesa furnace body, a stirring motor, a feeding module and a deslagging device, wherein an electric combustion machine is arranged at the bottom of one side of the furnace body; the furnace body is internally provided with a hearth; the stirring motor is fixedly connected with a stirring shaft by means of a gearbox; the stirring motor is arranged on the top of the hearth; the stirring shaft passes through the hearth and enters the hearth; the hearth is communicated with a condenser by means of a hose pipe; a storage tank is arranged under the condenser; the bottom of the deslagging device is communicated with a water tank by means of a pipeline; the feeding module is installed at the right upper corner of the furnace body; the feeding module comprises a feeding box, a driving motor, a drivinggrinding roller, a driven grinding roller, a cam, an air bag, an arc-shaped guide plate, a mounting plate, a blow head and an automatic door. Plexiglass particles are thrown to the middle upper partof the hearth by means of the air bag, thus being evenly dispersed, and avoiding the phenomenon that the production efficiency is affected due to the insufficient reaction caused by raw material accumulation in the hearth.

Description

technical field [0001] The invention belongs to the technical field of plexiglass recycling, in particular to a method for recycling waste plexiglass. Background technique [0002] Plexiglass composed of polymethyl methacrylate is widely used in various industries. However, using waste organic glass to crack and regenerate to obtain methyl methacrylate monomer to realize the recycling of organic glass is in line with the policy of circular economy and has good environmental, economic and social benefits, so it has developed rapidly in our country. [0003] In the prior art, some technical solutions of organic glass continuous cracking devices have also appeared. For example, a Chinese patent with application number 2016206959990 discloses an environmentally friendly continuous cracking device for waste organic glass plastics, including a furnace body, a stirring drive motor, a feeder and slag extractor, the stirring drive motor is fixedly connected to the stirring shaft thr...

Problems solved by technology

[0004] This technical solution can realize the continuous cracking of plexiglass, and the temperature, feeding and slag discharge can be controlled and adjusted. However, the raw material supply device of this solution makes the raw materials concentrate in the local position of the furnace body, resulting in the accumulation and distribution of raw materials. Inhomogeneity, which affects the efficiency of the cleavage reaction
